Easton flex markings

I typically play with a 54" - 55" shaft, so I do a fair bit of trimming to any sticks I grab. My sticks are basically Int height, but I'm hesitant to try an Int stick because of it's light flex (I really would like a proper height, 75/80 flex).

One thing that really intrigues me is Easton and how the rated flex is already a few inches down the shaft. Does anyone know if they also do this on shafts? I feel like a 75 flex Easton 1pc might be perfect (What's the markings read?). My current Warrior blades typically use 48.5"/49.5" shafts.

Would a chopped two piece Dynasty result in the same flex as a chopped ops Dynasty?

I used mostly 2 piece sticks but usually only Warrior blades, I'm just trying to find some consistency on shafts considering I cut a good deal off. I'm guessing using a Bauer/Easton shaft with the warrior blade would be an experiment if I like it or not?
